There was a sun... It's- just that we arrived in a sort of ... Plated underground. You had to stay there for a month before you could earn moving above ground. There were... reasons to move back down, like helping new arrivals get acquainted from your home world. Meaning, I don't really know how much time I spent down there. Some of us didn't really keep track at all.
